The UP-4slim ultra-compact installation loudspeaker is ideally suited for applications requiring a small, slim, aesthetically pleasing cabinet that delivers high sound pressure levels with low distortion and uniform coverage. The UP-4slim offers this exceptional audio performance in a compact self-powered package with a remote power supply. As a standalone loudspeaker, the UP-4slim is appropriate for vocal reinforcement, front'fill, and under balcony fill applications. The UP-4slim can be optionally paired with a Meyer Sound subwoofer to create a full'range system. One MM'10ACX can also power one UP-4slim. The UP-4slim is engineered to the same award-winning standards as all Meyer Sound IntelligentDC loudspeakers. Its on-board amplification and sophisticated signal processing provide the flat frequency and phase responses for which Meyer Sound loudspeakers are known. Its drivers are designed and manufactured at the Meyer Sound factory in Berkeley, California. The UP-4slim's high-frequency section includes a 1-inch metal dome tweeter on a constant-directivity, high-frequency horn. The low to mid'frequency section includes two 4-inch cone transducers that work in parallel at low frequencies to deliver a combined acoustic output. One of the drivers rolls off at higher frequencies to maintain constant directivity in the crossover region. The UP-4slim has very low distortion, boasts a wide operating frequency range (65 Hz " 18 kHz), and linear peak SPL of 116.5 dB with crest factor >16.5 dB using M-noise4. With a smooth and consistent 100 coverage, fewer loudspeakers can cover a larger area, reducing system cost while maintaining the highest sound quality. With IntelligentDC technology, the UP-4slim receives DC power and balanced audio from a single Phoenix 5-pin connector. Powering the loudspeakers from a Meyer Sound IntelligentDC external power supply eliminates the need for wiring conduits while still preserving the advantages of self-powered systems. The Meyer Sound IntelligentDC power supplies distribute DC power and balanced audio to UP-4slim loudspeakers or other Meyer Sound IntelligentDC loudspeakers. The UP-4slim's amplifier and signal'processing circuits store DC power and tolerate voltage drops, thereby accommodating light-gauge cables and lengthy cable runs. Composite multiconductor cables, such as Belden 1502 or equivalent, can deliver both DC power and balanced audio to loudspeakers at cable lengths up to 150 feet with just 1 dB of loss in peak SPL using 18 AWG wire for power. Longer cable lengths are possible with heavier gauge wires. The 2-channel MPS-482HP power supply is ideal for applications requiring a small channel count or the capability for mounting the supply remotely on a wall or ceiling, while the 8-channel MPS-488X is ideal for larger installations.
